CryoProbe System (Optional)
The Bruker CryoProbe
TM
Accessory for the AVANCE NMR spectrometers offers dramatic
increases in signal to noise ratio, stability, and ease of use. For site planning details for the
CryoProbe accessory, refer to
CryoProbe and Other Accessories [
.
The CryoProbe system consists of the following components:

Figure 3.2: CryoProbe System
1.
The
CryoProbe
represents the NMR probe inside the magnet bore, and is cooled
by cryogenic helium gas. The CryoProbe maximizes efficiency and reduces
thermal noise, thus enhancing the signal-to-noise ratio.
2.
The
CryoCooling unit
contains a cryocooler, a cryocontroller, a vacuum system,
and He transfer lines. The unit cools compressed helium gas by expansion and
provides and maintains the vacuum insulation. The unit also supervises all
CryoProbe operations.
3.
The research grade
Helium gas cylinder
provides research grade helium gas
(99.9999%) at high pressure (min. 200 bar) for flushing the probe prior to a cool-
down cycle. The cylinder includes a regulator, an outlet valve, and a charging
hose.
4.
A
transfer line
supports provide support for the probe and isolates the probe
against vibrations.
5.
The
He compressor
provides compressed helium gas to the CryoCooling unit.
The compressor connects to the CryoCooling unit by means of helium gas
pressure lines. The indoor water-cooled helium compressor is shown to the right.
Other models, including indoor air-cooled and outdoor air-cooled, are available.
